I have a Sears- Free Spirit treadmill Model 309150
When I try to calibrate it it runs for a very long time at full speed (over an hour) without actually calibrating. Without calibrating, the incline does not work. Should this process take over an hour?

I have a spirit xt8 and finally got the calibration instructions. I had to contact the store that I purchased it at in order to get it as the manual does not address this at all. I would be happy to email you the instructions. contact me at
